DUMPING-CAR.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed November 16,1907. Serial No. 402,380.

T 0 all whom it may concern:

Be it known that I, ARTHUR G. BROWN, a subject of the King of GreatBritain, residing at Spokane, in I State of Washington, have invented ordiscovered certain new and useful Improvements in Dumping-Oars, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention has for its object to provide an improved turn-table,dumping car, for use 1 in railroad construction or other purposes, andwhich is of such form that it can be easily turned, and which comprisesdevices for holding the end gate in a raised position when the car bodyis'tilted in dumping, all as will be hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side view of the improveddumping car, and Fig, 2 is a similar view but showing the carbody turnedon the truck frame and tilted for dumping. Fig. 3 is a cross-sectionalview of the improved car. Fig. 4 is a top view of the truck frame, andFig. 5 a bottom view of the turn-table.

Referring to the drawings, 12 denotes the truck frame which is mountedon the trucks in any suitable manner. Attached to the truck frame is alower bolster-plate 13 and radial plates 14, said radial plates beingprovided with recesses for the reception of antifriction balls 15 heldin place by cap-plates 16. Supported by the truck frame is a turn table17 provided beneath with the upper bolster plate 13, and with a ring 19of iron or other suitable metal serving as a track running over theanti-friction balls 15. The turn-table is pivoted to the truck frame ina well-known manner by a suitable king bolt 20.

Mounted on the turn-table is a bottom casting'21 for the dumping hinge,said casting preferably having open slots 22 receiving the pins ortrunnions 23 of the upper dump castmg 24 suitably attached to thecentral cross beam 25 of the car box or body 26, said car body normallyresting on a cross-beam 27 which is in turn supported by a second andshorter cross-beam 28, and both of said cross beams are secured to theturn table 17 by suitable bolts 29.

To the front end-gate 30 of the car box or body are attachedlongitudinal supporting bars 31 pivoted at 32 to brackets or links 33secured to said car body, the said bars 31 extending through suitableloops on the standards 34 bolted to the cross beam 27, as shown thecounty of Spokane and 1 in Fig. 3, strips 35 being secured to saidstandards to afford the loops through which the said bars 31 passbeneath studs or rollers 36 interposed between said strips and saidstandards. Said studs or rollers 36 engage the upper sides of the bars31 and serve as stops to prevent the forward ends of said bars fromlifting when the car-body is tilted in dumping. To the lower part of theend gate 30 are detaehably attached hooked links 37 the rear ends ofwhich are jointed on the pivots 32 so that the said hooked links can bedisengaged from the said end gate, if desired, to permit the latter toswing outward slightly to afford .more opening, if required, in dumpmg.

Owing to the fact that the pivots of the bars 31 are slightly rearwardof the pivot or center of motion of the dumping car body it follows thatwhen the front end of said car body is tilted down, in dumping, thefront ends of said bars 31 will simultaneously be lifted slightly, thusraising the end gate 30 a little, and as the pivotal points 32 of thesaid bars will not pass very much forward of the pivotal point of thecar body when the latter is lifted, in dumping, the said end-gate 30will be held in a raised position, as shown in Fig. 2, when the frontend of the dumping car box is tilted downward. In this tilting operationthe loops of the standards 34, through which the said bars 31 pass,permit suitable endwise movement of said bars relative to saidstandards, to allow for proper freedom of action of the parts. \Vhen thedumping car body is again restored to its normal horizontal position theend gate 30 will close the end of said box by assuming the positionshown in Fig. 1.

The car body is preferably provided with a removable rear end gate 38consisting of a suitable plank held in place by one or more standards 39attached to a cross-beam 40. Any suitable detachable connection forretaining the dumping car body in its normal or horizontal position maybe employed, said connection, as herein shown, consisting of the linkdevice 41.

From the foregoing it will be apparent that the invention provides aturn-table dumping car of such construction that the car box or body maybe easily swung around sidewise for dumping; even when heavily loaded;while the end gate mechanism is of such construction that the end gateat the front end 1 of the car box will be opened automatically when thecar is dumped by the movement of the tilting car body away from the endgate, and the end of the car body will be automatically closed when saidcar body is re stored to its normal horizontal position. Also the opencasting, affording the pivot or hinge of the dumping car, is of suchconstruction that should the car be accidentally capsized in dumping thecar body will become disengaged from the turn-table, and the latter,being loosely attached to the truckframe, will become disengaged fromthe latter, so that the parts can be more easily handled in restoringthe car to its proper position if all of these parts were permanently attached together.

Having thus described my invention I claim and desire to secure byLetters Patent:

1. In a dumping car, the combination with a tilting body, of a suitablesupport on which said body is mounted, standards rigid with saidsupport, an end-gate, longitudinal bars by which said end gate issupported, said bars being pivotally connected with said body andengaging stops on said standards, so that when the said body is tiltedthe said longitudinal bars may move forward and said end-gate will beheld in a raised position, thus permitting the contents of the tiltingbody to be discharged.

2. In a dumping car, the combination with a tilting body, of a suitablesupport on which said body is mounted, standards rigid with saidsupport, rollers on said standards an end-gate, longitudinal bars bywhich said end gate is supported, said bars being pivotally connectedwith said body and passing beneath said rollers so that when the saidbody is tilted the said longitudinal bars may move forward and saidend-gate will be held in a raised position, thus permitting the contentsof the tilting body to be discharged.

3. In a dumping car, the combination with a tilting body, of a suitableturn-table on which said body is mounted, standards rigid with saidturn-table, rollers on said standards, an end-gate, longitudinal bars bywhich said end gate is supported, said bars being pivotally connectedwith said body and passing beneath and in contact with said rollerswhich serve as stops for preventing upward movements of the rear ends ofsaid bars, While permitting free longitudinal movements thereof, so thatwhen the said body is tilted said bars may move freely forward and thesaid end gate will be held in a raised position, thus permitting thecontents of the tilting body to be discharged.

4. In a dumping car, the combination with a suitable truck, of aturn-table mounted on said truck and loosely connected therewith, atilting car body having an open hinged connection with the saidturn-table; whereby should the car be accidentally overturned in dumpingthe car body may become detached from the turn-table, and the turntablefrom the truck, to permit these parts to be more easily handled inrestoring the car to its proper position.

5. In a dumping car, the combination of a suitable truck provided withanti-friction balls, a turn-table pivotally mounted on said truck andhaving a circular plate to engage said balls, and a tilting car-bodypivotally mounted on said turn-table, said turn-table being providedwith standards rearward of the hinge or pivot of said tilting body, saidstandards having loops, an end-gate, and longitudinal bars supportingsaid end-gate and passing loosely through said loops and engaging stopson said standards.

6. In a dumping car, the combination of the truck 12 having the recessedradial plates 14, anti-friction balls, cap-plates by which said ballsare suitably confined to said radial plates, a turn-table having thebearing ring 19 running over said balls, and the tilting body mounted onsaid turn-table.

7. In a dumping car, the combination of the truck 12 having the recessedradial plates 14, anti-friction balls, cap-plates by which said ballsare suitably confined to said radial plates, a turn-table having thebearing-ring 19 running over said balls, and the tilting body mounted onsaid turn-table, said tilting body being provided with an endgate, andmeans for holding said end-gate in a raised position when said body istilted.

In testimony whereof I affix my signature, in presence of two witnesses.
